IMPROVEMENT IN WIND-WHEELS.

Specification forming part of Letters Patent N 0. 222,072, datedNovember 25, 1879; application filed May 10, 1879.

To all whom it may concern Be it known that I, HENRY B. MYERs, of

, a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of a face of my wind-wheel.Fig. 2 is a sideelevation view; and Fig. 3 is a plan View.

Identical parts in the drawings are designated and referred to by thesame letters.

My invention relates to windmills; and it consists in two wind-wheelsconstructed to be driven in opposite directions by the wind, bothdriving one power-shaft, one wheel being the same diameter as the eye ofthe larger wheel,

constructed for the purposes herein more fully set forth.

A represents the windmill-frame. B is a hollow stem passing through thetop of the frame and resting in a proper socket at b. This stem orstandard turns freely in its position. The upper portion of thisstandard is bifurcated, and provides abearing of sut'fioient length toproperly hold the shafts of the two wind-wheels O and D.

0 is the smaller wheel of the two, and is constructed with rigidfeathers. Upon the inner end of the shaft of this wheel there is abevel-pinion, G, which meshes with the bevelpinion 0 This pinion O isrigidly attached to the power-shaft E, which is located in the hollow ofthe standard 13.

D is the larger wind-wheel. The distance between the inner ends ofopposite feathers or the eye of this wheel is about equal to the extremeoutside diameter'of smaller wheel, 0. Upon the inner end of the shaft ofthis wheel D there is also'a bevel-pinion, D, which is larger than thepinion G. This pinion meshes with a bevel-pinion, D which is alsorigidly attached to the shaft E. This pinion D is larger than thecorresponding pinion G and the parts described are so constructed andarranged that they revolve the same number of times in a given number ofrevolutions of the shaft E, and, being located upon opposite sides ofthe shaft E, their reverse motions drive the shaft E in the samedirection. 7

F is a frame for supporting the vanes. This frame is supported by thecurved braces ff, which are securely attached to the head of thestandardB.

G, -H, and K are the vanes for controlling the position of thewind-wheels in relation to the wind, and they are firmly supported intheir position by their stems g, h, and it, rest ing in their respectiveboxes g, h, and k.

The vanes G and H are for holding the wind-wheels facing the current ofthe wind for operation, and to retain them in their position.

Their stems are journaled in their boxes, and provided with a weightedarm, 9 and 71/ These stems g and h are also provided with arms 9 and 71.

The stem 70 is provided with an arm, k", which is connected with theangled lever L by the connecting-rod Z. This lever L is pivoted to theframe F near its center, and its lower arm provided with a weight, If,and its upper one with a vane, 1 This stem 70 is also provided with thearms is and H, which engage the arms 9 and 7&3. I

The operation of my invention is as follows: When the mill is set foraction, the vanes G and H are vertical and the vane K is horizontal. Incase the wind is too strong in its current the vane Z is blown back, theweight I being properly adjusted. The motion of the lever L revolves thestem 70 and turns the vane K up to wind, and at the same time the arms kand k engage the arms and h", and turn the vanes Gr and H down in ahorizontal position, when the vane K, controlling the windwheels, willcause them to be turned. from the wind.

The vane Z is set a little quartering, so as to be acted upon by strongcurrents; but as they subside, or the mill is partially turned fromthem, the vane l is returned, wholly or in part, by the weight I.

The weighted arms g'-and it return the vanes G and H to a verticalposition, wholly or in part, as the current of the wind moderates orincreases in force.

By this means I am enabled to automatically protect my windmill frominjury, and at the to the mill.

In case it is desired to stop the mill, it is done by drawing down upona rope which is attached by a half or quarter turn to the shaft k, andpasses down the inside of the hollow shaft or stem B.

Instead of the arms g and k engaging the arms 70 and I0 I may usebevel-gear if I find it preferable, situated upon their respectiveshafts or stems, and meshing, to secure more certain and positiveaction.

I do not wish to confine myself to windwheels of the exact proportionsherein described, as it is my purposeto have one wheel about the size ofthe eye of the other; nor do I wish to confine myself to the relativeposition of the wind-wheels, as it may be found expedient to place thelarger wheel to the windward of the smaller one. I may also dis-,pensewith one of the bevel-gears on the poweran eye in diameter aboutequal to the outside diameter of wheel 0, as and for the purposes setforth.

2. In a windmill the vanes G and H, provided with the weighted arms andh and arms g and h, in combination with vane K, provided with the stem70, arms k and k and k, and the lever L7 provided with the weight I andvane l as and for the purposes substantially as set forth.

3. In a windmill, the lever L, provided with the vane Z and theadjustable weight I, in combination with the stem 75 and vanes Gr and H,as and for the purposes substantially as set forth.

4.. In a windmill, the wind-wheels 0' and D, in combination with thepower-shaft E, the hollow stem B, the frame F, and vanes G, H, and K,and the lever L, provided with the adjustable weight Z and vane Z setquartering, as and for the purposes substantially as set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
